Using files stored outside the database creates all sorts of problems. For
starters you lose ACID guaranties. I would prefer to keep them in database.
We did a lot of experiments with Large Objects and they really worked fine
(stored hundreds of LOBs ranging from a few MB up to 1GB). Postgres does a
really good job with Large Objects. If it was not the pg_dump problem I
would not hesitate to use LOBs.
